the sleeve is at the forward limit of its movement u on the bar-15.

citizen of the United States, residing at Thes eeve is provided with an upstanding Superior, in the county of Don las and State of Wisconsin, have invente certain new and useful Improvements in'O crating and Latch Devices for Doors, of wich the following is a specification. y

The invention has for an object to eiiectappara us,.

improvements in door contro adaptable to use in the opening and closing of doors, and for holding doors in open position, or closed position; The device is especially useful in connection with double swinging doors, such as doors of garages and other structures.

It is an important aim of the invention to Additional objects, advantages and fea-' tures of invention reside in the construction, arrangement and combination of parts as may be understood from the following description and drawings, in which Flgure 1 is a top new of one embodiment of the invention, with certain supporting structural parts omitted,

Fig. 2 is a detail elevation of the sliding element, its mounting, and means for holdin% it in open position,

ig. 3 is a detail of a familiar construction of a spring hinge.

There is illustrated formally, a small building 10, having doors 11 hinged at the sides of the door opening 12, to swing outwardly, their radius being such that they will meet midway of the opening. Upon suitable cross pieces 13 and 14 adjacent the top of the door opening, a guide bar 15 is fixed, at right angles to the plane of the doors when closed and in line with the line u on which they meet. The bar 15 has slida le thereon a sleeve 30, having lateral ears at the side, in which there are pivoted links 18 extending respectively therefrom and pivotally connected to the respective doors 11 adjacent their swinging edges. The links 18 are of a length to connect the doors with the sleeve when the doors are at full 0 en position as illustrated in Fig. 1, and w on rear end of the lever. A. spring 38 is connected between the lever 32 and the sleeve to hold the bolt yieldingly in engaged position. The bolt is of a length to clear the bar 15 when raised a slight distance, the bar having latch openings 40 both adjacent the rear end and adjacent the forward end, in which the bolt 36 may engage.

In use when the doors are moved into closed position, the bolt 36 will latch in the openin 40 adjacent the rear end of the bar 15, .100 'ng the doors in closed position. When it is desired to open the doors, a pull upon the cable 33 will operate the lever 32 withdrawing the bolt 36, and continued force applied to the cable will then move the sleeve 30 forwardly, operating the doors, and moving them to open position. When the parts are thus positioned, release of the cable 33 will permit the bolt 36 to engage in the forward opening 40 of the bar 15 when alined therewith. It is an especial advantage of this device that it may be operated for opening or closin by the driver of a motor vehicle without 1; e driver leav-' ing the vehicle, by extending the cable 33 to a location convenlent for manipulation from the vehicle, and utilizing a spring element to yieldingly close the doors after any familiar method. Ordinar s ring hinges may be employed at 41, as lndlcated in Fig. 1 of the drawings. When operatin the mechanism for opening of the doors, y operating the cable to draw the sleeve 30 forwardly so that the bolt 36 is slightl forward of the openin 40 and then quic ly releasing the cable, t e bolt will sprmg downwardly and 5 matically latching itself when movedto closed position, as before indicated. If desired, spring devices or weights of familiar form ma be used for closing the doors.

What is claimed is 1. In a device of the character described, the combination of hinged door elements, means acting to close the doors yieldingly, a rectilinear guide adjacent the swinging edges of and vertical to the plane of the closed doors, a slide thereon, link elements connected to respective doors adjacent their swinging edges and to the slide, spring-pressed holding means to hold the slide at the limits of its movement, and cable operated means to release the holding means extending forwardly from the slide and engaged therewith whereby draft on the cable will release said holdin means, and continued draft on the cable will move the doors toward open position.

2. A hinged door synchronizing and fastening device of the character described comprising a horizontal bar, a sleeve slidable thereon, a vertical bolt guide on the sleeve, a bolt reciprocable therein to engage the bar, said bar having bolt'openings-therethrough adjacent respective limits of movement of the slide, an arm on the sleeve forwardly of the bolt, a lever on the arm connected at one end to the bolt, an anti-friction guide 4 on the sleeve forwardly of the arm, a cable connected to the forward end of the lever and extended forwardly throu h said guide, and yielding means to move t e bolt to engaged position.

- a In testimony whereof'I have aflixed my signature in presence of two witnesses.
